根因分析
需求说明符包含格式错误的版本操作符,没有版本号,导致 pip 的需求解析器失败。
English
The requirement specifier contains a malformed version operator with no version number, causing pip's requirement parser to fail.
解决方案
-
99% 成功率
Replace 'requests===' with a valid specifier, e.g. `pip install 'requests==2.31.0'` or `pip install requests`.
-
97% 成功率
Use quotes: `pip install 'requests>=2,<3'` so the shell doesn't strip operators.
无效尝试
常见但无效的做法:
-
95% 失败
Cache is unrelated to parsing the requirement string; the syntax error remains.
-
90% 失败
The parser is already correct; the user-supplied requirement string is invalid.
